Ossipee Mountains
The Ossipee Mountains are a small mountain range in the New England state of New Hampshire, United States. The remains of an ancient volcanic ring dike,[1] they lie north of Lake Winnipesaukee, east of Squam Lake, and south of the Sandwich Range, the southernmost of the White Mountains. 2,990 ft (910 m) Mount Shaw is their highest point.
Geology and physiography
[edit]The Ossipee Mountains are the remains of a 125 million year-old volcanic ring dike,[1] the remnant of a Cretaceous stratovolcano of the later White Mountain igneous province. The complex is circular in plain view and has a diameter of 14 km.[2] The ring-dike complex is easily identified on satellite images, with its southeast edge located about 5 miles (8 km) northwest of the town center of Ossipee.
